Study Notes
World War 2 and the Development of Electronic Computing
- World War 2 spurred many advancements in electronic computing, shifting away from mechanical parts like gears or belts.
- The German forces used the Enigma machine to encode secret messages, which led to the development of the Bombe computer by the British under Alan Turing's leadership.
- The Bombe computer was a forerunner of modern computers, capable of deciphering the code created by the German Enigma machine.
Early Computers
- ENIAC (Electronic Numerical Integrator and Calculator) was completed in the 1940s as a general-purpose computer, used by the US army to calculate firing tables for various weapons.
- EDVAC (Electronic Discrete Variable Automatic Computer) followed ENIAC, being the first computer to use binary instead of decimal.
- UNIVAC (Universal Automatic Computer) was the first commercially produced electronic computer in the US, used for census taking and capable of performing thousands of calculations in seconds.
Personal Computers
- The 1970s saw the development of personal computers, with the Apple Computer being created in 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne.
- Bill Gates and Paul Allen founded Microsoft in 1975, releasing the Windows operating system in 1985, which offered users a graphical interface.
Advances in Computing Technology
- Throughout the 20th century, technology was developed to create smaller computers while decreasing processing time, leading to the development of personal devices such as:
- Graphing Calculators
- Desktop or personal computers (PC)
- Laptop or notebook computers
- Tablets
